DS18B20 DS2484 drivers

I want to connect some DS18B20 temperature sensors to an AVR (ATMega) using the Dallas 1 Wire (which is what these sensors use :-) ).

I plan to use the DS2484 I2C to One Wire bridge chip to remove the critical one wire timing requirements from the AVR. The DS2484 is a handy chip but it is very low level, so you have to send commands for each 1 wire bit over the I2C.

Has anyone used these chips and therefore written some drivers?

(There seems to be lots of Arduino code around).

For only 1 DS18B20 you can try my simple DS18B20-Program.

Thanks guys, I will check them out. I would still like a driver for the DS2484 though. Might have to write one.
